The vast majority of patients undergoing surgery for breast cancer in Toronto still have conventional Breast Conserving Surgery (BCS) or mastectomy as their primary oncologic operation. The Princess Margaret Cancer Center and the Women’s College Hospital in Toronto

represent a unique environment with respect to its large volume of breast cancer patients. In addition, these hospitals have begun to offer OPBS procedures as part of standard breast cancer care, making them among the firsts hospitals to do so in the province. Currently, there is very limited data on the outcomes of oncoplastic procedures in Toronto and Canada.

 

The primary objective of our study is to assess the clinical and patient reported outcomes with OPBS when compared to conventional BCS or mastectomy.
